Got myself a mid sized piano (110 height). Great tone in upper area but lower area is collapsed compared to a full size piano (of course).

Has anyone tried to reduce acoustic shortcuts in smaller pianos, using bass-reflex or passive radiators?


Not that it covers my original idea about fixing the shortcut in the resonance-plate but good advices at:


  • Avoid wall-to-wall placement (avoid fluttering)
  • Explore open angle to back wall
  • Open doors to adjacent rooms
  • 2
    Where it is in the room will also have an important bearing.

    Yeah I mean putting it in a corner might be your best bet Nov 24, 2020 at 17:30

    Have you tried playing with top open or the front panel off?

This might be a bit overkill but some may find it of interest..

A solution could be to pick the sound of the piano, EQ it in order, for instance to boost a bit the bass, and broadcasted in the room thanks to very clean loudspeakers...

If the electronic broadcast part bothers you, or if you want to add a bit of caché to your room you can also use an acoustic resonator ;).

  • Ah, an acoustic resonator could be it! Very interesting! :)

  • @Teson I am sure you will have more chance / easier time, playing with the room and panels, but I thought it was worth mentioning. Good luck!
